3 Claims.

TheY present invention relates to improvements in perpetual calendars and .is particularly directed to a date indicator for writing implements or the like.

An object of the invention is lto provide aadjusting the calendar carrying means s-o as to keep said calendarA up to date.y

A furthery object of the invention is4 to provide a complete date indicator,-positively setting forth the. month, the day of the week, and numerical day of the month, which may be enclosed in a writing implement without. interfering with the mechanism or meansV for providing writing material..

A still further objectof the inventionis to provide a simplified and positive acting means for operating a calendar which whenmanipulated to indicate a desired time period, will remain stationary until operated again.

Other objects will .be apparent from the fol'- lowing specification and drawing, in'which:

Fig. 1 is. an elevational View of a pencil showing my calendar and operating means therefor associated with it.

Fig. 2 is an elevational view of the calendar operating mechanism.

Fig. 3 is an enlarged, fragmentary, cross-sectional view taken on line 3-3 oi Fig. 1.

Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 3.

Fig. 5 is a cross-sectional view taken on line 5-5 of Fig. 3.

Fig. 6 is a perspective view carriage of my device.

My date indicator is shown in the drawing as associated with a mechanical pencil I which has a hollow barrel II open at its upper end and provided at its lower end with rotatable reduced portion I2 for holding and advancing lead I3 by means of any well-known mechanism I4 extending upwardly into and centrally of the barrel.

An elongated, rotatable tube I is located centrally in the barrel so that its lower end encircles the lead holding and advancing mechanism I4 whilst the upper portion I6 projects from the open end of the barrel. A cylinder I'I is located adjacent the lower portion of the tube and is precluded from rotation thereon by means kof the cylinder cylinder andadapted-toA be received man elongated slot I9 formed in the tube.'

The cylinder I1 is longitudinally movable on the tube, said movement beingy controlled from theexterior of the barrel by means ofv a carriage member 20 (Figs.v 2, 3' and 6)", which consists of a narro-w straight` portion 2| bent soas to'form @ringer-piece 22, and having disposedy at' right angles two spaced discs 23 provided with annular openings 24. Theopenings are adapted toencircle the tube whilstthe discfportions freely engage the ends of said cylinder'. The linger-piece 22 as shown in ,Figi 3', is accessible from the eX- teriory of vthe `barrel bythe formation in `the `barrel of an elongated slot 25 which determines the longitudinal limits of 'motion of the'carriage and the cylinder I'I controlled'by it.

The longitudinally movable cylinder ILI carries calendar indicia 26 whichare disposed in curvilinear and longitudinal rows as indicated in Fig. 2. The indicia are disposed longitudinally'from the bottom to the top in numerical order, and

are' so arranged rthat-in any fseven consecutive rows oflongitudinal figures, the first Vligure of each curvilinear row will consecutively follow the rst numeralof the curvilinear row to the left of it. VThe barrel has a, window 2l formed through it so that any selected.'sevenconsecutive, curvilinear rows off figures may be visible through it from the exteriorof the barrel. Adjacent the window 21 and in alignment with the curvilinear rows of figures 26, are initials 28 which indicate the names of the days of the week. Accordingly, the cylinder II is moved longitudinally by means of the finger-piece 22 so that number one of the indicia 26 is brought in alignment with the dat7 of the week 28, on which the first of the calendar month occurs to thereby permit the mechanism to function as a calendar for said month, it being only necessary to rotate the cylinder from right to left to bring each succeeding week of the month into the opening 26. The rotation of the cylinder II is controlled exteriorly of the barrel by means of a friction cap 29 which is fastened to the projecting end I6 of the tube. Manual rotation of said cap is transmitted to the tube and as the cylinder is precluded from rotation relative to the tube, it will also be rotated.

Encircling the upper end of the tube I5 is a second cylinder 30 havingprinted thereon in an aligned curvilinear row the names of the month 3| in consecutive order. In longitudinal alignment with each name of the month is positioned a numeral 32 indicating the number of days in of inturned lugs I8 formed in the edges of the 55 said month. A window 33 is formed in the barrel through which the name of one month is visible from the exterior of the barrel. The means for controlling the rotation of the cylinder 30 from the exterior of the barrel consists of a knurled annular disc 34 which is formed integrally on the cylinder 30.

The means for holding the calendar mechanism within the pencil consists of an annular groove 35 formed in the interior surface of the barrel adjacent the open end thereof. An annular shoulder portion 38 on the cylinder 3U is received and held in said groove 35 whilst the lower end of said cylinder is in engagement with a Washer 3'! which is rigidly fastened to the periphery of the tube I5.

It is contemplated that my mechanical date indicator may be associated with other writing implements such as fountain pens orthe like. In

the event a fountain pen is provided with my mechanism, the ink sack thereof may be inserted centrally in the lower end of the tube I5.

What is claimed is:

1. A mechanical date indicator for a Writing implement having a barrel with an open end therein, comprising a rotatable tube disposed centrally within the barrel and projecting from the open end, a longitudinally movable calendar indicia cylinder encircling the tube, means for precluding rotation of said cylinder relative to the tube, a carriage member engaging the ends of said cylinder, a finger-piece on the carriage member extending through the barrel, a longitudinally stationary calendar indicia cylinder on the tube having a knobformed thereon disposed outside the open end of the barrel, an annular Ywindows formed through the barrel in alignmentwith the indicia bearing cylinders, and station- 'ary calibrations adjacent the Window in alignment with the longitudinally movable cylinder to which the indicia on'said cylinder may be intelligently referred. A

2. A mechanical date indicator for a writing implement having a barrel with an open end therein, comprising a rotatable tube disposed centrally within the barrel and projecting from the open end, a longitudinally movable calendar indicia cylinder encircling the tube, means for precluding rotation of said cylinder relative to the tube, a carriage member engaging the ends of said cylinder, a finger-.piece on the carriage member extending through the barrel, a longitudinally stationary calendar indicia cylinder on the tube having a knob formed thereon disposed outside the open end of the barrel, means for holding the latter cylinder in rotatable engagement with the barrel, means associated with the tube and the longitudinally stationary cylinder for precluding withdrawal of said tube, a friction cap for the projecting end of the tube, windows formed through the barrel in alignment with the indicia-bearing cylinders, and stationary calibrations adjacent the window in alignment with the longitudinally movable cylinder to which the indicia on said cylinder may be intelligently referred.

3. A mechanical date indicator for a Writing implement having a barrel with an open top and with means'for providing writing material extending centrally from the bottom of the barrel into the interior thereof comprising a rotatable tube encircling the means for providing writing material and projecting from the open end of the barrel, a longitudinally movable calendar indicia cylinder having an outside diameter less than the inside diameter, of the barrel adapted to surround the tube, means for preventing rotation of the cylinder relative to the tube, a longitudinal slot formed in the barrel, a carriage member for controlling the longitudinal movement of the cylinder and comprising end ring portions encircling the tube and engaging the ends of the cylinder, said ring portions having a diameter equal to that of the cylinder, a narrow straight portion lying between the cylinder and the barrel for connecting the end ring portions, a finger-piece on the straight portion for extending through the slot, a Window formed in the barrel, and stationary calibrations adjacent the window to which the indicia on the cylinder may be intelligently referred.
